n. pl. teeth (tēth)
One of a set of hard, bonelike structures rooted in sockets in the jaws of vertebrates, typically composed of a core of soft pulp surrounded by a layer of hard dentin that is coated with cement or enamel at the crown and used chiefly for biting or chewing food or as a means of attack or defense.
The outer covering of a vertebrate animal, consisting of two layers of cells, a thick inner layer (the dermis) and a thin outer layer (the epidermis). Structures such as hair, scales, or feathers are contained in the skin, as are fat cells, sweat glands, and sensory receptors. Skin provides a protective barrier against disease-causing microorganisms and against the sun's ultraviolet rays. In warm-blooded animals, it aids in temperature regulation, as by insulating against the cold.
Plural teeth (tēth)
The external tissue that covers the body. As the body's largest organ (it makes up about one twenty-fifth of an adult's weight), the skin serves as a waterproof covering that helps keep out pathogens and protects against temperature extremes and sunlight. The skin also contains special nerve endings that respond to touch, pressure, heat, and cold. The skin has an outer layer, or epidermis, and a layer immediately below, called the dermis.
A hard structure, embedded in the jaws of the mouth, that functions in chewing. The tooth consists of a crown, covered with hard white enamel; a root, which anchors the tooth to the jawbone; and a “neck” between the crown and the root, covered by the gum. Most of the tooth is made up of dentin, which is located directly below the enamel. The soft interior of the tooth, the pulp, contains nerves and blood vessels. Humans have molars for grinding food, incisors for cutting, and canines and bicuspids for tearing.
